Luthe Lab:  Mighty Maize Macerates Malicious Herbivores

Students and post-docs in my lab are investing the mechanism of herbivore resistance in genotypes of maize that have been developed by classical plant breeding.  These genotypes show remarkable resistance to feeding by fall armyworm and a number of additional Lepidopteran species.  Recent studies suggest that these genotypes also are resistant to feeding by Western corn rootworm suggesting that there is above and below ground communication in these plants.  We are interested in understanding the plant’s defensive mechanisms, signaling pathways that activate them, and herbivore response to these defenses.
